[INET]: Add missed tunnel64_err handler
The tunnel64_protocol uses the tunnel4_protocol's err_handler and thus calls the tunnel4_protocol's handlers. This is not very good, as in case of (icmp) error the wrong error handlers will be called (e.g. ipip ones instead of sit) and this won't be noticed at all, because the error is not reported.
